Introduction
Compression Artifacts
Digital video compression has introduced a new set of picture artifacts known in the
industry as «mosquito noise» and «blocking artifacts». These new degradations coexist
with analog video noise and become quite objectionable when seen on today’s large
screen displays (see images below).
Algolith’s Flea has been engineered to reduce the appearance of noise and compression
artifacts, allowing for a much better viewing experience.
Mosquito Noise Analog Type Noise Blocking Effect
Flea
Flea is a three-dimensional digital noise reduction processor, designed to clean up
signals from DVD Players/Recorders, Satellite Receivers, Cable Decoders, PVRs and
other digital devices using MPEG-2 compression.
Flea performs four distinct image noise reduction techniques.
1- Mosquito noise is removed, using Algolith’s proprietary region-based algorithm.
2- Block Artifact Reduction (BAR) blends and diminishes the inherent 8 x 8 pixel block
structures of MPEG2 images.
3- Algolith’s advanced motion adaptive temporal filtering eliminates “bad reception
and low light” noise.
4- Flea provides image enhancement using non-linear filters for exceptionally sharp
and noise free pictures.
